Aging and Inhibition of a Prepotent Motor Response during an Ongoing Action

ABSTRACT

Inhibitory functions are key mechanisms underlying age related decline (Park & Gutchess, 2000 Park, D. C. and Gutchess, A. H. 2000. “Cognitive aging and everyday life”. In Cognitive aging: A primer, Edited by: Park, D. and Schwartz, N. Hove, , UK: Psychology Press.  [Google Scholar], in: Cognitive aging: A primer. Hove: Psychology Press), yet few studies have investigated their impact on everyday tasks involving action as well as cognition. Using an everyday-based go/no-go task we devised a motor analogy of traditional neuropsychological tests to investigate in 134 older (aged 60–88) and 133 younger adults (aged 20–59) the ability to inhibit a prepotent motor response during an ongoing action. Older adults produced more inhibition failures as expected, but more strikingly inhibitory errors were not all or none; even when the inappropriate response was successfully inhibited, difficulties controlling ongoing movements emerged from as young as people in their 40s. The ability to inhibit therefore does not ensure control of ongoing tasks, and traditional cognitive tests may be unable to detect such difficulties. Furthermore, performance did not covary with education or action speed. Implications for neuropsychological theory and assessing/enhancing functional ability are discussed.     

Toward a psychoeducational curriculum for training sport-injury rehabilitation personnel

Abstract

This paper addresses significant gaps in the wining programs of sport-injury rehabilitation personnel (SIRPs) in the psychology ma. The main aim of the article is to offer for consideration a psychoeducational curriculum that is specifically designed for the training of professionals who work with injured athletes. In addition to describing the applied implications of research on the psychological aspects of sport injuries for professional practitioners. reviews of what SIRPs consider is missing-but-desirable in their professional wining. and the effectiveness of certain psychological strategies, are presented. Finally. an overview of a prototypical three-year curriculum for professional training programs is outlined.     

“We Told You that's How They Are”: Responses To White Women in Abusive Intimate Relationships with Men of Color

The urging by interracial couples to be accepted as “normal” couples may present as challenging if problems arise in the relationship; especially if those “problems” are of an abusive or violent nature. Drawing on semi-structured, in-depth interviews we analyze the experiences of White women in abusive intimate relationships with men of color. We query the struggles of the women negotiating these relationships and explore the responses the women receive by family, friends, the general public, and workers in the criminal justice system and social and medical services. We argue that White women abused by men of color face additional challenges because of outsiders' disapproving views of the interracial nature of the relationships.     

Effects of Music on Physiological Arousal: Explorations into Tempo and Genre

Two experiments explore the validity of conceptualizing musical beats as auditory structural features and the potential for increases in tempo to lead to greater sympathetic arousal, measured using skin conductance. In the first experiment, fast- and slow-paced rock and classical music excerpts were compared to silence. As expected, skin conductance response (SCR) frequency was greater during music processing than during silence. Skin conductance level (SCL) data showed that fast-paced music elicits greater activation than slow-paced music. Genre significantly interacted with tempo in SCR frequency, with faster tempo increasing activation for classical music and decreasing it for rock music. A second experiment was conducted to explore the possibility that the presumed familiarity of the genre led to this interaction. Although further evidence was found for conceptualizing musical beat onsets as auditory structure, the familiarity explanation was not supported.     

Encouraging Bystanders to Promote Positive Parenting and Prevent Child Maltreatment in Retail Settings: Results of an Exploratory Qualitative Study

Community-level bystander approaches with media campaigns have successfully reduced sexual violence, but these programs have not been developed for child maltreatment prevention. This study informs the development of such programs in retail settings. Data were collected using focus groups with parents (n = 29) and surveys with child abuse experts (n = 10). Participants were asked how retail environments and employees could support parents during shopping excursions and what employees should do if they witnessed a concerning interaction. Participants highlighted (a) the need for in-depth training of employees to engage with parents and children to promote positive interactions and intervene in concerning situations; (b) the importance of the built environment (i.e., physical design and layout) to reduce stress and establish positive social norms through store-wide messaging; and (c) the role of parents in establishing expectations and actively including children in shopping. Future research should test approaches to training and engaging retail employees as supportive bystanders.     

Age differences in personality traits from 10 to 65: Big Five domains and facets in a large cross-sectional sample

Hypotheses about mean-level age differences in the Big Five personality domains, as well as 10 more specific facet traits within those domains, were tested in a very large cross-sectional sample (N = 1,267,218) of children, adolescents, and adults (ages 10-65) assessed over the World Wide Web. The results supported several conclusions. First, late childhood and adolescence were key periods. Across these years, age trends for some traits (a) were especially pronounced, (b) were in a direction different from the corresponding adult trends, or (c) first indicated the presence of gender differences. Second, there were some negative trends in psychosocial maturity from late childhood into adolescence, whereas adult trends were overwhelmingly in the direction of greater maturity and adjustment. Third, the related but distinguishable facet traits within each broad Big Five domain often showed distinct age trends, highlighting the importance of facet-level research for understanding life span age differences in personality.     

The Secret Lives of Liberals and Conservatives: Personality Profiles,Interaction Styles,and the Things They Leave Behind

Although skeptics continue to doubt that most people are “ideological,” evidence suggests that meaningful left‐right differences do exist and that they may be rooted in basic personality dispositions, that is, relatively stable individual differences in psychological needs, motives, and orientations toward the world. Seventy‐five years of theory and research on personality and political orientation has produced a long list of dispositions, traits, and behaviors. Applying a theory of ideology as motivated social cognition and a “Big Five” framework, we find that two traits, Openness to New Experiences and Conscientiousness, parsimoniously capture many of the ways in which individual differences underlying political orientation have been conceptualized. In three studies we investigate the relationship between personality and political orientation using multiple domains and measurement techniques, including: self‐reported personality assessment; nonverbal behavior in the context of social interaction; and personal possessions and the characteristics of living and working spaces. We obtained consistent and converging evidence that personality differences between liberals and conservatives are robust, replicable, and behaviorally significant, especially with respect to social (vs. economic) dimensions of ideology. In general, liberals are more open‐minded, creative, curious, and novelty seeking, whereas conservatives are more orderly, conventional, and better organized.     

Locating attractiveness in the face space: Faces are more attractive when closer to <Emphasis Type="Italic">their</Emphasis> group prototype

Face attractiveness relates positively to the mathematical averageness of a face, but how close attractive faces of varying groups are to their own and to other-group prototypes in the face space remains unclear. In two studies, we modeled the locations of attractive and unattractive Caucasian, Asian, and African faces in participants’ face space using multidimensional scaling analysis. In all three sets of faces, facial attractiveness significantly increased with the absolute proximity of a face to its group prototype. In the case of Caucasian and African faces (Study 1), facial attractiveness also tended to increase with the absolute proximity of a face to the other-group prototype. However, this association was at best marginal, and it became clearly nonsignificant when distance to the own-group prototype was controlled for. Thus, the present research provides original evidence that average features of faces contribute to increasing their attractiveness, but only when these features are average to the group to which a face belongs. The present research also offers further support to face space models of people’s mental representations of faces.     

Development and validation of a Dutch translation of the Big Five Inventory (BFI)

In this article, we describe the translation and validation of the Dutch Big Five Inventory (BFI; John & Srivastava, 1999), a short instrument designed to measure the Big Five factors of personality. We obtained evidence of the instrument's good psychometric properties in terms of factorial equivalence to the English original and other BFI translations and the relative independence and internal consistency of the five scales. The findings suggest that the instrument can be used in diverse age groups without substantial changes in factor structure. The Dutch BFI scales showed similar demographic correlates as the English original, with higher Agreeableness and Conscientiousness and lower Neuroticism values in older participants, higher Neuroticism values in women, and higher Openness and Conscientiousness values in better educated participants. Use of the Dutch BFI will allow researchers to integrate their findings with the extant Big Five research literature. The brevity of the instrument will be appealing to researchers who are concerned about taxing the time and motivation of their participants.
